Distribution of Human Norovirus in the Coastal Waters of South Korea
Fig 6
Comparison of the number of human norovirus (HNoV) sequences isolated from each water type by sampling month.
The number of HNoV sequences isolated is shown in the horizontal stacked bar charts. Charts show genogroups (a–c = GI; d–f = GII) and water types (a and d = both stream and estuary; b and e = stream; c and f = estuary). In each panel, the HNoV sequences are sorted by sampling month (vertical axis), and the internal patterning of the horizontal bars (total HNoV sequences in a sampling month) indicates the number of sequences of each genotype.
